关节镜下B-PT-B治疗后交叉韧带损伤

目的：探讨关节镜下应用骨-髌腱-骨(B—W—B)重建后交叉韧带临床疗效。方法：选择11例膝后交叉韧带断裂患者，在关节镜下行B—W—B重建后交叉韧带(PCL)，观察手术前后膝关节症状，后抽屉试验，Lachman试验的变化。结果：术后随访1年至1年5个月(平均1年4个月)，膝关节活动范围正常，稳定性明显改善，均无其他合并症，均恢复正常活动。结论：PCL断裂并发关节不稳应进行重建手术。B—W—B符合后交叉韧带的功能要求。在关节镜下手术，操作方便，创伤小，恢复快，疗效满意。

Bone-patellar tendon-bone graft reconstruct arthroscopically posterior cruciate ligament injury

Objective: To explore clinical outcomes of reconstructing arthroscopically posterior cruciate ligament(PCL) by bone-patellar tendon-bone (B-PT-B).Method: 11 patients with PCL injuries were underwent bone-patellar tendon-bone graft reconstruction .The symptom of knees before operation were contrasted with those of after operation , posterior drawer test and lachmam test were observed. Result: All cases were followed-up ranging from 1 years to 1.5 years (averagely 1.4 years ) , motion rang of knees were not only normal but also perfect stability , The function of knees obviously recover which were no complications .Conclusion: It is necessary to reconstructed for those patients who suffered from PCL breaking-up. B-PT-B reconstruction arthroscopical was not only convenient but also satisfactory effect.
